SHOE-SUPPGRTIN G JACK.

Patented Nov. 30, 1915.

Application filed January 19, 1914. Serial N 0. 813,071.

To all whom it may concern Be it known that I, HERMAN A. DAVEN- ronr, a citizen of the United States, residing at Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Shoe-Supporting Jacks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The'invention relates to shoe supporting jacks such as are used in sole laying and other shoe machines for supporting lasted shoes.

The object of the invention is to provide a novel and improved construction which will enable a comparatively heavy pressure to be applied to the sole or bottom of the shoe supported on the last without danger of breaking or injuring the last.

To this end the invention consists in the features of construction and combinations of parts hereinafter described and referred to in the claims.

The invention will be readily understood from an inspection of the accompanying drawings and the following detailed description of the mechanism illustrated therein.

In the drawings: Figure l is an elevation showing so much of a sole laying machine as is necessary to illustrate the application of the present invention thereto; Fig. 2 is a detailed sectional view on line 2-2, Fig. 1; Fig. 3 is a horizontal sectional view on line 33, Fig. 1; and Fig. 4 is a detailed end view of the instep pad and its support.

In the drawings the invention is illustrated as embodied in a sole laying machine for temporarily securing outsoles to lasted shoes. In this machine a heavy pressure is applied to the sole by a pressure pad 2 while the lasted shoe is supported by a jack carried on the cross-head 4.. As shown, the jack comprises a heel supporting post 6 on which the usual heel pin 8 is pivotally mounted, and a toe supporting post 10 carrying the toe and instep engaging devices embodying the present invention. These devices comprise a toe pad 12 and an lnstep pad 14, which are so mounted that they may rock longitudinally to firmly position themselves in engagement with the toe and instep, respectively, and are also so mounted that they move laterally to properly center themselves in engagement with the shoe, or to accommodate themselves to either right or left shoes. The pads are also preferably mounted to swing laterally in accordance with the lateral swing'of the shoe.

y thus mounting the toe and instep pads thelr accurate and firm engagement with the toe and instep of the particular shoe being operated upon is insured so that the last will be firmly supported at both the toe and instep, thus enabling it to with stand the heavy pressure requisite to properly lay the sole against the bottom of the shoe and last. i i

As shown, the toe pad 12 is pivotally supported upon one end of the support 16 so that the pad may rock longitudinally to position itself against the shoe. The instep pad 14; may be similarly inountedupon the support 16, but is preferably secured in fixed position upon the opposite end of the support, as shown in the drawings. The support 16 carrying the toe and instep pads is mounted to rock longitudinally in a carrier block 18 so that the pads may accommodate themselves to the arch of the shoe and firmly position themselves against the last. The carrier block is provided with a segmental guideway which receives the segmental flange'20 on the upper edge of the support 16 and the flangeis held in the guideway by the retaining plates 22 which are secured to the carrier block by the screws 24. The flange on the pad carrier is free to slide in the guideway in the support and the rocking movements of the support are limited by a stop pin 26 arranged to engage the heads of the screws 24. A disk 28 ispressed against the upper surface of the flange 20 by a spring 30 and acts to frictionally resist the rocking movement of the pad support.

The carrier block 18 is provided at its upper end with a head 32 mounted to slide laterally in the guideway formed in the lower end of the toe supporting post 10. This enables the toe and instep pads to move laterally to position themselves upon the last, or to be moved laterally to bring them into the proper position to act on either a right or left shoe. The sides of the head 32 of the head. This screw taper from the-center of the head, as inclicated in Fig. swing laterally in either direction to a lim ited extent. This enables the toe and instep pads to swing laterally to accommodate themselves to the lateral swing of the last, whether of a right or left shoe. The carrier blockis retained in its guideway by a screw an, the end of which is arranged to play within a recess 36 formed in the upper face 7 may also be used to clamp the carrier block 18 in any adjusted position in case it is found desirable to. do so. in operating upon any particular style or shape of shoe.

lVhile the invention has been shown and described as embodied in the jack of a sole laying machine, it will be understood that it is notlimited in its application to such a machine, but may be embodied with advantage in other forms of jacks, or in jacks support mounted for the rocking support.

adapted for use 1n other machines in which it is desirable to firmly support the last so that it may effectively withstand a comparatively heavy pressure. It will also be understood that the specific arrangement and construction of parts shown and described is not essential to the broader features of the invention, but may be varied or modified as found desirable or best suited to the construction of jack or machine in whichit is to be embodied.

Having explained the nature and object of the invention and specifically described one form of mechanism in which it may be embodied, what is claimed is 1. A shoe supporting jack, having in combination, toe and instep pads, a longitudinally rocking support on which the pads are mounted, and a laterally movable carrier 2. A shoe supporting jack, having in combination, toe and instep pads, a longitudinally rocking support on which the pads are mounted, and a carrier for the rocking to move laterally and to Copies of this patent may be obtained for 3, so that the carrier block may swing in accordance with the lateralswing of the last.

. 8. A shoe supporting jack, having in combination, toe and instep pads mounted to rock longitudinally and to swing laterally in accordance with the lateral swing of the last, and means for supporting the pads.

4:. A shoe supporting jack, having in combination, a heel support, a toe support, and pads for engaging the toe and instep mounted 011 the toe support to rock longitudinally to accommodate themselves to the arch of the last and to swing date themselves to the lateral swing of the.

last. a

5. A shoe supporting jack, having in combination, a heel support, a toe support, a carrier block mounted to move laterally on the toe support, a support mounted to rock longitudinally on thecarrier, and toe and instep pads mounted on the rocking support. 6. A shoe supporting jack, having, in combination, toe and instep pads, a support on which the pads are mounted, and a carrier block provided with a segmental guideway in which the pad support is freely movable. 7. A shoe supporting jack, having in combination, a heel support, a toe support, a carrier block mounted to move laterally on the toe support, a segmental guideway in the carrier block, a pad support mounted to move in the guideway, a toe pad pivotally mounted on the support, and an instep pad mounted on the support.

8. A shoe supporting jack, having, in combination, toe and instep pads, a support on which the pads are mounted, a carrier block provided with a segmental guideway in which the support is movable, and a toe support provided withalateral guideway in which the carrier block is movable.
